I can already tell a difference in the a/c--no more burning rubber smell in the cabin! This job took me about 2 hours due to mostly the wiper arm removal and old lower flashing removal and installation. Installation of the cowl itself involved removing two clips and connecting the hose bracket to the cowl, which merely slides up (the black square thing in the cowl pic).

Anyway, I highly recommend you check out your cowl and flashing situation, especially if you've already gone through the trouble of replacing your upper windshield flashing and you have an older model e39.

Hope I inspired some of you to do this as well; you'll love yourself for it!

Well, here are some pics of my satelite antennas (SIRIUS and Magellan navigation, respectively) and a corresponding pic of my busy but friendly cockpit, which I merely took since I had my camera handy!
